Description

Technical Field

[0001] The invention relates to the technical field of river-related construction of water conservancy projects, and in particular to a method for intercepting yellow muddy water in river-related operations. Background Art

[0002] Yellow mud water is a kind of yellow mud with a certain viscosity, which usually appears at the construction site. It is caused by the accumulation of impurities such as silt during construction, which makes the water contain a large amount of suspended particulate matter. During the construction process, yellow mud water easily flows into the original river channel, causing a great impact on the water quality of the river channel. At the same time, soil erosion on the site affects the blockage of the downstream river channel, causing a great negative impact on the corporate image, leading to delays in construction progress and reduced project quality.

[0003] Conventional method for treating yellow mud water in construction sites: yellow mud water is concentrated in the construction site, flows into the tertiary sedimentation tank through drainage pipes or drainage ditches, and is discharged into the river after sedimentation and filtration in the sedimentation tank. It occupies a large construction site and affects the overall construction arrangement. During the rainy season, the amount of rain is large, which may cause the drainage facilities to fail to drain in time, and the yellow mud water directly enters the river, causing a greater negative impact on the enterprise. At the same time, the setting of drainage facilities and sedimentation tanks wastes a lot of manpower and material resources, which is neither economical nor safe. Therefore, a method of intercepting yellow mud water using the original river channel is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose a method for intercepting yellow mud water in river-related operations.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A method for intercepting yellow muddy water in river-related operations comprises the following steps: S1. Construct an interception area in the original river channel, and vertically drive multiple installation columns that are higher than the construction site into the original river channel to ensure its firmness, to ensure the stability of the interception area, and to increase its anti-slip and anti-overturning capabilities; S2. Lay two layers of geotextiles at the bottom of the river channel in the interception area to ensure that the bottom of the river channel is cleaned and tidy in time after the construction is completed; S3. Use galvanized wire mesh + geotextile combination to enclose the middle of the installation column, and set up a filter screen facing the construction site. After the yellow mud water is filtered and separated by the combination of galvanized wire mesh, filter screen and geotextile, the yellow mud is left in the interception area, and the treated clean water flows directly into the river; S4. During the construction process, if it is found that the speed at which the geotextile absorbs yellow mud water slows down, replace the geotextile to maintain the speed at which the geotextile absorbs yellow mud water.

[0006] In some embodiments, the installation spacing of the columns in step S1 is maintained at 1-1.5 m.

The inner end of the rocker is hinged with a connecting rod, and the lower end of the connecting rod is hinged to the upper surface of the transmission rod.

[0011] In some embodiments, a stabilizing component for improving the fixing effect of the first column is disposed inside the lower end of the first column, and the stabilizing component includes a plurality of top plates that slide symmetrically on the surface of the first column and a push block for pushing the plurality of top plates to slide outward, and the plurality of top plates slide inward through a second spring, and the upper surface of the push block is connected to the lower end of the transmission rod through a third spring and a connecting block.

[0012] In some embodiments, a valve for inflating the airbag is fixedly connected to the side surface of the upper end of the first column, the valve is connected to the airbag through a hose, and a pressure gauge is provided on the surface of the valve.

[0013] Compared with the prior art, the present invention provides a method for intercepting yellow mud water in river-related operations, which has the following beneficial effects.

[0014] 1. The present invention sets up a muddy water interception zone in the original river channel and uses a galvanized wire mesh + geotextile + filter mesh combination for enclosure to achieve the effect of water permeability but mud impermeability, so that the muddy water is simply filtered in the interception zone and then discharged into the original river channel, effectively solving the problem of muddy water flowing into the river channel due to the construction site being higher than the original river channel elevation.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-12 , a method for intercepting yellow mud water in river-related operations, comprising the following steps; An interception area 11 is constructed in the original river channel 12, and multiple installation columns 13 that are higher than the construction site 10 are vertically driven into the original river channel 12. The installation spacing of the installation columns 13 is maintained at 1-1.5m, and they embrace the construction site 10 in an arc shape to ensure its firmness. Two layers of geotextiles 16 are laid at the bottom of the river channel in the interception area 11.

[0032] It can be understood that by setting up the installation columns 13, the stability of the interception area 11 can be ensured, and its anti-slip and anti-overturning capabilities can be increased. By laying two layers of geotextiles 16 on the bottom of the river channel in the interception area 11, it is convenient to clean and tidy up the river channel bottom in time after the construction is completed.

[0033] Specifically, a galvanized wire mesh 14 + geotextile 16 combination is used for enclosure in the middle of the installation column 13, and a filter screen 15 is set. The arrangement order of the galvanized wire mesh 14, the geotextile 16, and the filter screen 15 is galvanized wire mesh 14, the filter screen 15, the geotextile 16, the filter screen 15, and the galvanized wire mesh 14.

[0034] It can be understood that, in the order of galvanized wire mesh 14, filter screen 15, geotextile 16, filter screen 15, and galvanized wire mesh 14, they are all clamped and fixed by installing columns 13. The galvanized wire mesh 14 can increase the strength. The combination of filter screen 15 and geotextile 16 can filter the muddy water to achieve the effect of water permeability but mud impermeability, leaving the mud in the interception area 11, and the filtered clean water directly flows into the river channel, effectively solving the problem of muddy water flowing into the river channel due to the construction site 10 being higher than the original river channel elevation. It can not only intercept muddy water from entering the river, but also reduce the construction difficulty and speed up the overall construction progress. During the construction process, if it is found that the speed of geotextile 16 absorbing muddy water slows down, the geotextile 16 is replaced to maintain the speed of geotextile 16 absorbing muddy water.

[0035] Specifically, the installation column 13 includes a first column 1, an L-shaped notch is opened on the side of the first column 1, and the second column 2 is fixed on the surface of the notch. A gap for installing galvanized wire mesh 14, filter screen 15, and geotextile 16 is formed between the first column 1 and the second column 2. The first column 1 is horizontally slidably connected with a clamping member 3 that cooperates with the second column 2 to clamp the geotextile 16. The inner wall of the first column 1 is opened with a plurality of sliding grooves 301, and a plurality of fixing blocks 302 are fixedly connected to the surface of the clamping member 3. The clamping member 3 is slidably connected inside the plurality of sliding grooves 301 through the plurality of fixing blocks 302. A V-shaped groove is provided on the side of the clamping member 3 close to the second column 2, and a V-shaped protrusion that cooperates with the V-shaped groove is provided on the side of the second column 2 close to the clamping member 3.

[0036] It is understandable that the galvanized wire mesh 14, the filter screen 15, and the geotextile 16 are placed into the gap in sequence, so that the clamping member 3 slides in the first column 1, thereby improving the clamping effect under the cooperation of the V-shaped groove and the V-shaped protrusion.

[0037] Specifically, a transmission assembly 4 for driving the clamping member 3 to slide is arranged inside the first column 1, and the transmission assembly 4 includes a transmission rod 401 that slides vertically inside the first column 1, and a plurality of guide blocks 405 are fixedly connected to the inner side of the first column 1, and the transmission rod 401 is slidably connected to the surfaces of the plurality of guide blocks 405, and a plurality of first inclined blocks 402 are fixed to the array of the transmission rod 401 on one side close to the clamping member 3, and a plurality of second inclined blocks 403 that cooperate with the first inclined blocks 402 are distributed in an array inside the clamping member 3, and a plurality of first springs 404 for resetting the clamping member 3 are distributed in an array inside the clamping member 3, and the other ends of the plurality of first springs 404 are fixedly connected to the sides of the plurality of guide blocks 405, and the first springs 404 are tension springs.

[0038] It can be understood that, by the transmission rod 401 sliding downward on the surface of multiple guide blocks 405, the first inclined block 402 is driven to push the second inclined block 403 and the clamping member 3 to slide toward the outside of the first column 1, so that the clamping member 3 generates a clamping force. With the cooperation of multiple first inclined blocks 402 and multiple second inclined blocks 403, the thrust of the first inclined block 402 on the clamping member 3 is evenly distributed. By setting the first spring 404, it is convenient to pull the clamping member 3 to slide back to the inside of the first column 1.

[0039] Specifically, a buoyancy top pressure assembly 5 for driving the transmission rod 401 to slide downward is provided on the upper end side of the first column 1, and the buoyancy top pressure assembly 5 includes a seesaw 501 hinged on the upper end side of the first column 1, one end of the seesaw 501 is arranged inside the first column 1, an air bag 503 is fixedly connected to the lower surface of the outer end of the seesaw 501, a connecting rod 502 is hinged at the inner end of the seesaw 501, and the lower end of the connecting rod 502 is hinged to the upper surface of the transmission rod 401, and a valve 7 for inflating the air bag 503 is fixedly connected to the upper end side of the first column 1, the valve 7 is connected to the air bag 503 through a hose, and a pressure gauge 8 is provided on the surface of the valve 7.

[0040] It can be understood that by placing the airbag 503 into the river water of the original river channel 12, using an external air pump to connect to the valve 7, inflating the airbag 503 through the air pump and the hose, and observing the pressure in the airbag 503 through the barometer 8, when the pressure in the inner bag reaches the preset value, the inflation work is terminated and the valve 7 is closed, and the river water generates an upward buoyancy on the inflated airbag 503, so that the airbag 503 drives the seesaw 501 to rotate, and drives the connecting rod 502 and the transmission rod 401 to move downward through the inner end of the seesaw 501.

[0041] Specifically, a stabilizing component 6 for improving the fixing effect of the first column 1 is arranged inside the lower end of the first column 1, and the stabilizing component 6 includes a plurality of top plates 602 that slide symmetrically on the surface of the first column 1 and a push block 601 for pushing the plurality of top plates 602 to slide outward, the push block 601 is slidably connected to the inside of the lower end of the first column 1, the inner ends of the plurality of top plates 602 are provided with inclined surfaces, both sides of the push block 601 are fixedly connected with top blocks that push the top plates 602 to slide, the surface of the top block is provided with inclined surfaces, the plurality of top plates 602 are L-shaped, the plurality of top plates 602 slide inwardly through a second spring 603, both ends of the second spring 603 are fixedly connected to the surface of the top plate 602 and the inside of the first column 1, the upper surface of the push block 601 is fixedly connected to a third spring 604, the upper end of the third spring 604 is fixedly connected to a connecting block 605, the connecting block 605 is slidably connected to the inside of the first column 1, and the connecting block 605 is fixedly connected to the lower end of the transmission rod 401.

[0042] It can be understood that when the transmission rod 401 moves downward, the push block 601 is driven to move downward through the connecting block 605 and the third spring 604. With the cooperation of the top block and the top plate 602, the top plate 602 extends out of the range of the first column 1. The top plate 602 increases the resistance to the upward movement of the mounting column 13 to prevent the buoyancy of the airbag 503 from causing the mounting column 13 to loosen. By setting the third spring 604, a buffer is formed when the connecting block 605 pushes the push block 601 to prevent the limitation of the descending distance of the push block 601 from affecting the descending distance of the transmission rod 401, resulting in insufficient thrust on the clamping member 3, thereby affecting the clamping effect on the galvanized wire mesh 14, the filter screen 15, and the geotextile 16.

[0043] Specifically, a retaining ring 9 is fixedly connected to the lower end surface of the first column 1 , and a conical surface is provided at the lower end of the first column 1 .

[0044] It is understandable that by providing the retaining ring 9, the fixing depth of the installation column 13 can be limited when the installation column 13 is fixed, and the installation column 13 can be easily inserted into the river bottom under the action of the conical surface.

[0045] In the present invention, a plurality of installation columns 13 higher than the construction site 10 are vertically driven into the original river channel 12, and surround the construction site 10 in an arc shape, and two layers of geotextiles 16 are laid at the bottom of the river channel in the interception area 11, and are arranged in the gap between the first column 1 and the second column 2 in the order of galvanized wire mesh 14, filter screen 15, geotextile 16, filter screen 15, and galvanized wire mesh 14, and an external air pump is connected to the valve 7, and the air bag 503 is inflated through the air pump and the hose, and the pressure in the air bag 503 is observed through the barometer 8. When the pressure in the inner bag reaches a preset value, the air bag 503 is finally inflated. Stop the inflation work and close the valve 7, the river water generates an upward buoyancy on the inflated airbag 503, so that the airbag 503 drives the seesaw 501 to rotate, and the inner end of the seesaw 501 drives the connecting rod 502 and the transmission rod 401 to move downward, and the transmission rod 401 slides downward on the surface of multiple guide blocks 405, driving the first inclined block 402 to push the second inclined block 403 and the clamping member 3 to slide toward the outside of the first column 1, so that the clamping member 3 generates a clamping force, and the clamping member 3 cooperates with the second column 2 to clamp and fix the galvanized wire mesh 14, the filter screen 15, and the geotextile 16. At the same time, when When the transmission rod 401 moves downward, the push block 601 is driven to move downward through the connecting block 605 and the third spring 604. With the cooperation of the top block and the top plate 602, the top plate 602 is extended out of the range of the first column 1. The top plate 602 increases the resistance of the installation column 13 to move upward, and the buoyancy of the airbag 503 is prevented from causing the installation column 13 to loosen. The muddy water generated during the construction process flows into the interception area 11, and the muddy water is filtered through the filter screen 15 and the geotextile 16, leaving the mud in the interception area 11. The filtered clean water directly flows into the river. When the construction is completed, the interception area 1 is cleared. 1, and then open valve 7 to discharge the gas in the airbag 503. When the airbag 503 loses buoyancy, the transmission rod 401 loses its downward thrust, so that the first spring 404 pulls the clamping member 3 to slide into the first column 1. With the cooperation of the second inclined block 403 and the first inclined block 402, the transmission rod 401 slides upward. At the same time, the push block 601 is pulled upward by the connecting block 605 and the third spring 604 to slide, so that the second spring 603 drives the top plate 602 to slide into the first column 1, and the top plate 602 is retracted into the first column 1, so that the installation column 13 can be taken out and recovered.
